The Louisiana Department of Transportation and Development rehabilitated a 50-year-old interstate crossing over the Mississippi River in Madison Parish.
Built in 1973, the I-20 Mississippi River Bridge connects Madison Parish in Louisiana to Warren County, MS, and provides one of the few interstate crossings over the river.
The $30 million project, which began in January 2019, was completed in May 2021, and provided a number of significant repairs including an overlay on the bridge deck, upgraded electrical system, and new roadway lighting components.
The old deck was resurfaced with new concrete to improve traction and preserve the structural aspects of the bridge flooring. The current electrical circuits were replaced, in addition to the replacement of nearly 100 roadway lighting fixtures with a modern LED system.
Roadway fiber optics were also replaced with new cameras and radar, which are integrated into Mississippi's IT network.
Additionally, selected bridge bearings were adapted to provide the ability to reposition the bridge truss upriver as necessary. The steel structural connections at certain locations on the bridge were modified to improve resilience against all loads and conditions.
New navigational and aerial beacons were also installed, along with improvements to the bridge monitoring system and ehancements to the inspection access walkways.
